Y., ASSIGNOR TO CHEER FARE REGISTER COMPANY OF DAYTON, OHIO, A CORPORATION OF NEW YORK REGISTERING DEVICE Application filed October 17, 1924. Serial No. 744,1 28.

This invention relates to a detent for holdas a hubodometer. The ordinary hubodom- 'eter comprises a reglstermg device mounted within the hub cap of a wheel, the travel of which 1s to be measured. The actuating device for the registerlng mechanism 1s of such n a character that the rotaton of the hub relashaping of the pawl is a more or less difiitive to the fixed axle on which the wheel is mounted will cause the operation of the reg istering device. In order that such a registering device may be applied to wheels of different diameters the driving mechanism usually includes a pawl and ratchet mecha-' nism, the ratchet wheel of which isremovable so that ratchet wheels of diflerent sizes may be inserted in the mechanism to accom- 0 modate the same to wheels of difierent diameters. The actuating pawl for the ratchet wheel may be adjusted or changed to accommodate it to different ratchet wheels as may be desired. It has been customary to mount 5 the detent pawl, which prevents the reverse movement of the ratchet wheel, on a fixed axis and it has been necessary to reshape or cut away the pawl to accommodate itto ratchet wheels of difierent sizes. This recult and tedious operation and adds considerable to the expense of constructing and installing the device. I

One object of the present invention is to provide a pawl which can be readily accommodated to ratchet wheels of different sizes without reshaping or modifying the pawl itself in any way. i

A further object of the invention is to provide an adjustable supporting device upon. which the pawl may be mounted and the adjustment of which will so shift the'position of the axis of the pawl as to properly accommodate it to ratchet wheels of diflerent sizes.

A further object of the invention is to provide such a device which will be very simple in its construction and which may be very easily adjusted.

Other objects of the invention willappear as the mechanism is described in detail.

In the accompanying drawings Fig. 1 is a longitudinalsectional view of a hubodometer embodying my invention taken on the line 1-1 of Fig. 2; Fig. 2 is a front elevation of the registering mechanism partly broken away; and Fig. 3 is a detail view of the 0pcrating device for the actuating pawl.

In these drawings I have illustrated one embodiment of my invention and have shown the same as applied to a hubodometer of a known construction but it will be understood that this particular embodiment has been chosen for the purpose of illustration only, that the invention may take various forms and may be applied to registering devices of various kinds without departing from the spirit thereof.

In that form of the device here shown the hubodometer as a whole is mounted in a. hub cap lwhich is secured to the hub of the wheel, the travel of which is to be measured. This wheel is rotatably mounted on a spindle or axle 2 and is secured thereon by a nut 3. In this particular device the registering mechanism does not rotate with the wheel'but remains stationary so that it is always in a position in which a. reading may readily be taken therefrom. The outer end of the hub cap is provided with an opening 4, preferably closed by a glass 5, through which the reading may be taken. The registering mechanism itself comprises a series of indicators or dials 6, of which there may be any suitable number. These dials are mounted on studs or pins 7 which in turn are mounted upon a supporting structure here shown in the form of aplate 8 which is so mounted in the hub cap that it will be held against rotation and the hubcap iiermitted to rotate about the same. To this end the plate 8 is here shown as having an inwardly extending shank or stud 9 journaled in a bcarin g 10 formed central of a plate or supporting member 11 which is rigidly secured to the hub cap so that it will revolve about the stud 9. In the present instance the plate 11 is provided with a screw threaded flange 12 which is threaded into a boss'13 forming part of the hub cap and extending about the sists of a train ofgearing 26 with which is opening or recess 14 in which the registering device is mounted. The stud 9 of the supporting plate 8 may be secured in the bee.-

ing 10 in anysuitable manner but, as here,

shown, a bearing plate "15 is rigidly secured to that end of thestud which projects beyond the inner end of the bearing 10and antifriction balls 16 are inserted between this hearing plate and the front wall of, an annular recess 1'? formed in the rotatable plate ll. The stud 9 is so connected with the spindle 2 that the supporting plate 8 and registering mechanism willbe held against rotation. As here shown a bracket 18 is rigidly secured to the bearing plate 15 and is provided with rearwardly extending arms 19 provided with longitudinal slots 20 to receive fingers 21 carried by a movable plate or spider 22. This spider has rearwardly' extending lugs 23 arranged to enter recesses 24: in the nut 3, which ismounted on the spindle 2. The spider 22 is yieldable toward and from the nut to permit the mechanism to be readily mounted 011 the hub of the wh el and a spring 25 confined between the spider 22 and the bearing plate l5'presses the spider toward the spindle and holds the lugs 23 in the recesses in the nut.

The driving mechanism for the registering device, consisting of the dials 6, may be of any suitable character but preferably eonconnected a ratchet wheel 27. Cooperating with the ratchet wheel is an actuating pawl 28 to which movement is imparted to rotate the ratchet wheel, this'movement being transmitted through the gear train to the dials. In the present device the pawl is carried by V apin 29 which is slidably mounted in a slot 30 formed in the supporting plate 8 and so arranged that the transverse movement of the pin in the slot 30 will impart the desired movement to thepawl. ed in an arm 31 formingpart of a yoke or eccentric strap 32,"which is mounted on an eccentric boss or bearing 33 secured to the rotatable plate '11 and preferably formed integral with the bearing 10. The pin 29 being mounted in the slot in the plate 8 it would be apparent that the yoke or eccentric strap will be held against rotation and that reciprocatory' movement will be imparted thereto by the rotation vof the eccentric boss within the same, thus causin the pawl to be actuated.

' The mechanism so far described can be applied to the hubs of wheels of various diameters without changing any part thereof, other than the ratchet wheel 27. Consequently the device can be manufactured complete without regard to the diameter of the wheel to which it is to be applied and when the device is to be installed it is provided with a ratchet wheel 27 of a size to properly operate the registering mechanism according to the diameter of the wheel; It is, of

The pin 29 is mountcourse, necessary that the ratchet wheel should be held against reverse movement and to this end a detent pawl 34 is provided and in order that this pawl may be accommodated to ratchet wheels of different sizes and may so engage the teeth of any such'ratchet wheel as to prevent all reverse movement or back lash on the part of that ratchet wheel I have mounted the pawl on an adjustable axis and. V

by adjusting the axis of the pawl the latter" may be properly positioned with relation to any ratchet wheel which may be inserted in the device. The pawl may be mounted in various ways but, in the device here shown, I have utilized an elongated supporting member or plate 35 which is pivotally mounted on the supporting plate 8 which carries the" registering mechanism, in the present instance'atthe center of said plate. present construction this plateis pivotally mounted on a screw threaded stud 36 by means of which the face plate 37 is secured to the supporting plate 8, this face plate havingopenings 38 through which the numerals on the various dials' may be read.

The pawl 34 is pivotally mounted on one endof the elongated plate or lever 35" and the other end of this plate is enlarged and provided" with an arcuate slot 39 through which extends a screw 40 which is threaded into the plate 8 and which when tightened down serves to hold the elongated plate 35 against all movement about its axis and to provide a fixed support for the pawl 34. It will be obvious that by loosening the screw 40 the plate 35 may be adjusted until the pawl 34: is'prope'rly positioned withrelation to the ratchet wheel and by'then tight- In the ening down the screw 40 the pawl is firmly secured in this position. The adjustment of the plate is thus very easily accomplished and the shifting of the axis of the pawl enablesthe latter to be very accurately positioned with relation to the ratchet wheel, thereby enabling the assembling and installation of the registering device to be quickly and easily accomplished.

VVhileI have shown and described one embodiment of my invention I wishitto be understood'that I do not desire to be limited to the details thereof as various modifications may appear to a person skilled in the art;
